A vortex flowmeter is a type of volumetric flow meter used across various industries to accurately measure the volume flow of liquids, gases, and steam.
- Principle of operation: It operates on the principle of vortex shedding, where an obstruction (bluff body) placed in the flow path creates alternating vortices downstream. The frequency of these vortices is directly proportional to the fluid’s velocity, allowing the flow rate to be determined.
- Key features:
- No moving parts, which results in low maintenance and high durability.
- Low pressure loss.
- Suitable for a wide range of fluids, including saturated and superheated steam, compressed air, and various liquids.
- Often features an on-screen display for transient flow, accumulated flow, and sometimes temperature and pressure readings.
- Can be equipped with temperature and pressure compensation for mass flow calculation.
- No moving parts, which results in low maintenance and high durability.
